Excerpts from Palin’s sometimes halting answers to Couric’s questions have been meted out on the broadcasts since last Wednesday. The clips have been picked up widely by the rest of the media, providing fodder for a new round of stories questioning her readiness and inspiring a "Saturday Night Live" sketch.

And it appears there may be one more controversial portion of Palin’s interview yet to air. Politico reported Monday that the Alaska governor was apparently stumped when Couric asked her to name a major Supreme Court decision other than Roe v. Wade.

A CBS News spokeswoman would not comment on the exchange. But during Tuesday's broadcast, Couric hinted that she queried both Palin and her Democratic counterpart about the topic for a series called “Vice Presidential Questions,” scheduled to air on the evening news tonight and Thursday.

“I ask Sarah Palin and Joe Biden everything from their views on a key Supreme Court decision to the separation of church and state,” the anchor said.

In a news release issued this morning, the network elaborated on the two questions posed to both vice presidential candidates that will air in a segment tonight. They were:

Why do you think Roe v. Wade is a good or bad decision? What other Supreme Court decisions do you disagree with?

Thomas Jefferson wrote about the First Amendment "building a wall of separation between church and state." Why do you think that is so important?

Will this be another "gotcha" moment for Palin? We'll have to wait to find out until this evening, when the segment airs on "CBS Evening News." (A hint that CBS may be sitting on something juicy: unlike other installments in its "Presidential Questions" series, the network is not releasing a transcript of the candidates' answers before the broadcast.)

For her part, Palin said she thinks it’s fair for the press to scrutinize her credentials and background.

“It would be sexist if the media were to hold back and not ask me about my experience, my vision, my principles, my values,” the GOP vice presidential candidate told Couric in yet another interview excerpt that aired on CBS’ “The Early Show” this morning.

UPDATE: Here's the transcript from tonight's "CBS Evening News":

COURIC: What other Supreme Court decisions do you disagree with?

PALIN: Well, let's see. There's --of course --in the great history of America rulings there have been rulings, that's never going to be absolute consensus by every American. And there are--those issues, again, like Roe v. Wade where I believe are best held on a state level and addressed there. So you know--going through the history of America, there would be others but--

COURIC: Can you think of any?

PALIN: Well, I could think of--of any again, that could be best dealt with on a more local level. Maybe I would take issue with. But you know, as mayor, and then as governor and even as a vice president, if I'm so privileged to serve, wouldn't be in a position of changing those things but in supporting the law of the land as it reads today.
